A pedestrian has been injured after being hit by a car following a series of crashes on Plymouth's roads.

There was a two-car crash on Outland Road earlier this afternoon, and a biker has also been taken to hospital after coming off their bike on Embankment Road.

The M5 remains closed northbound at Cullompton due to an ongoing police incident.

Both sides of the carriageway between J29 and J28 were closed earlier, and traffic is still at a standstill on the northbound carriageway while police respond to a man "on the wrong side of the railings" on a bridge.

Traffic is reportedly queuing for eight miles.
